Thanks for the support guys, means a lot! Don't forget to let me know what other basic subjects you think I should cover!
How about what gigabyte fucked up in the 10th series g1 gaming cards? I know for sure that 1070 has a fan issues like mine rx 480 which results in 1 fan sounding like rotor when first starting,also the insane temps on the rx 480 even after the bios update.I really wish I could make something about that cuz that card can't even hold the advertised clock on the box,it's always going up and down but never stable even on 72-3 C

Hi Jay, basic subject I've been meaning to suggest - what kind of temperatures we should be seeing inside of a water cooling loop - when we have a single pump and res config for say - 1 CPU and 2 GPUs (1080 GTX?).
What would be the ones we'd expect coming out of the rads, after it comes out of the GPU blocks, CPU block, etc. An overall overview of water temps in the system.
That Def Leppard reference :D
If we put the unlikely posibility of a pressure issue(dust entering without passing filter) aside, your system overall will likely benefit from this way of mounting the PSU. Here is why;
If the fan facing down is the normal way, then the electronics that produce heat inside the PSU will be mounted on the side facing up into the cabinet. The heat will then travel up, away from the fan, potentially get trapped between the electronics and the metal plate and heat it up. By mounting it with the fan facing up, the heat will travel up towards the fan and heat said metal plate less, in addition the previously warmer plate now face outwards against the cool air under the cabinet.
All in all I don't think it will make a noticeable difference and either way of mounting it is fine. Exception for the water cooled systems.
Hey Jay, as someone who's building my first PC soon, this was really helpful :)

@jackthegamer I'm in the process of building a computer for a blind friend. He has no use for pretty lights, but with the money he had available (spent just over $1k), I ended up having to buy some of the parts having LEDs. Now, if only I can find the power supply I'm giving him...it doesn't have LEDs.
I went off the advice of a friend and spent £100 on a gold efficiency psu that only draws what it uses not the full wattage

Hey Jay, I just had to say that I stumbled upon your channel a few months ago during my research trying to learn about gaming on computers and what i would need/want in my first gaming computer build. Thank you for having a huge selection of videos to watch that was able to explain complex ideas in a simple manner to a person who had zero experience in computer building or even how a computer functions. As I now find myself semi competent at the most basic level, I still enjoy watching any of the videos you create to stay present on any new hardware or how to benefit the hardware. Thank you Jay for being awesome!

I am planning my first ever build and I am currently watching all of your tutorial and build videos.
Going into detail really helps me build up the confidence to actually do this myself
and not spending my lifesavings on getting a prebuild which would probably be weaker :,)
Thanks for all your advice and stuff
Exactly the same!! On my next Pc ima build one and all these videos are very VERY!! helpful 😅
It'll take me at least a year before I can start to build my first PC, but I'm already checking out videos like this to be as informed as possible about every important detail. Great video, thanks!
Well?
Did u build it?
Pc update?
I am right now building my first computer and several of your videos have been so valuable!
I'd be interested in finding out just how much of that PSU exhaust loops back into the intake in the down configuration, as you suggested. I think the chassis exhaust fan above it should help keep that air on an aft trajectory. Plus, exhaust tends to be more directional than intake.
Jay is the only person I’m cool with belittling me lol this is probs my fav beginners guide type channel since the more I understand certain things you have videos about more intricate things it’s nice to know people can actually learn from your videos
@JayzTwoCents Great information. I'm glad that you go through all the points on the matter. I personally don't have to worry as my PSU mounts sideways in the Caorsair AIR 540. But when I build computers for others, this is good to keep in mind.
Thanks, and have a great day!
I'm planning on building a pc and I'm gathering all the knowledge I can. thanks for the tips jay!
My Gpu runs around 80C at full load, I don't think the psu will be pulling any "cool" air from it.
Mine is about 75 max unless the ambient outside is warmer than usual like peak summer, out of games 35 max, although I'm not running much from 2018-present
@Orion 8096758 if you have the right case fans the inside of you pc will not be warm. mine is generally about the same as the outside room temperature. (two front fans as intake, two top fans and a rear as exhaust)
and i know this as a fact as there's a temperature sensor inside
@Orion 8096758 He actually did address that with the entire circulation conversation when he started talking about the fan being faced down, he just didn't word it as such.
47 max here, though is that normal with older hardware?

This power supply video was really useful for today's build :D
Thank you!!
I'm not trying to be difficult or contradictory, but I for one would love to see some scientific testing done, over time, to verify these statements. I see a lot of videos about positive vs. negative pressure. I don't know what to believe and would love some actual proof. JayzTwoCents seems like the type to do the test and report back whether he was correct or not. Its why I watch, unwavering integrity.
What scientific proof do you need? If you draw more air in than you remove, the air will go out through the crevices of the case, thus resulting in less dust accumulating. You don't need "scientific testing" to verify common sense.
Without proof all you have is theory. Have you measured the amount of dust present in a case with positive pressure vs a case with negative pressure? If not, how can you be sure one is better than the other. Also, last I checked you are not Jay. So my comment was not directed at you.
+James Rhodes I've already does this test about air pressure with smoke
James Rhodes
I doubt there are many who would bother with that because a) it's something that is intuitive to most people, and b) experience confirms it but hey, good luck on finding those test results!
Do you have a video up? If so I missed it. I would like to see it. If not, maybe you could do one. I think it would be interesting to see.

Great topic. I have my EVGA Supernova 850w mounted down, because the case is on a solid surface, and there's a cover over it. I would recommend making sure you don't forget to check the bottom filter when you are cleaning your case. It is easy to forget about it. Mine needs regular cleaning, almost more than the internals.

Thank you so much for your channel! Just finished my first build, you were so helpful! Pics soon :)
Wow! This is perfect! I have a carpet but don't have much room to put it anywhere. My first power supply burned out due to dirt and dust intake from the bottom cent, because I didn't realize it sucked in at the time, so this would help with that.
After the first one burnt out, I managed to squeeze a table in, but now that I know this I might think about doing this!

Thank you for this video, was googling and researching on PSU exhaust placement, very helpful :)
Excellent video. My RMX850 is is one the way. This video answered my question about right side up or upside down. Again, Great Video!! Thanks!!
Hey Jay. Could you please do a video about PCI-E Overclocking with a couple of facts, benchmarks and risks? Theres pretty much no information on the internet about that topic and id like to know if you can gain performance from that. Best regards
As long as you can put a dust filter on the fan itself, then yeah, I'm with you. Just be careful doing any maintenance with the tower standing, because screws can fall into your PSU and it's a pain in the butt to get out. XD
this is a good idea to know. never would think about which ways to mount a psu. i had always mounted psu down and not up cause it was never a gaming pc. the gaming case ps i have i just learned something about which is a better way to mount the psu. so i did mount up to give inside my case a better air flow. thank you for this video. always learn something new know matter how old you are.
Hi Jay, Thanks for the video, very much enjoy your work for the community, inclusive informative and entertaining, very funny wonderful to see your creative style and energized delivery thank you from Australia.
Thanks for this video. I am building a budget rig around a 6600K and bought an old C70 case secondhand, which I freaking love the look of.
I was installing the PSU (EVGA 650 GA, also secondhand) last night and having this debate internally. I settled on fan up orientation for now but may give it further consideration.
@ 5:56 I screamed as loud as I could - "One lump or two!"
No no no, you are an expert user, I am an advanced user. I've watched a few of your videos over time and your expert views help sway my builds. Keep it up, subbed.
Thank you very much. I had just seen another build and I was asking why he installed with the fan on top.
How do you get a heating loop when the warm air exhausted from the power supply rises?
Orion 8096758 I mean I’m pretty sure that the fan facing upwards is an input fan and the warm air is pushed out the back (I think)
@@Ethan-rz6cx You are correct intake side on top with heat exhaust going out the back of the unit. In my recent build I had no choice but to place the intake down because of separate enclosure for power supply draws air from below. Without the enclosure I would have gone intake facing up, just to draw heat from inside the box out.
When the PSU is sucking air in from below and letting it push itself out the back, there is still a suction pressure from beneath that will make even the hot air go down. You are correct that hot air rises in cold air, however, the rate at which this happens is far slower than you may expect, especially when we are talking only a few degrees difference.
"Endless supply of content topics" No pun intended
A powerful statement
I felt alot of energy in this comment
Thank you for making this video. Your videos are really useful to computer builder enthusiasts like me.
Thanks for this video. While I have been around PCs since the dawn of time (Tandy TRS-80, Commodore PET, Apple II), and I have built a few PCs in my time, I have never seen anything about mounting a power supply with the fan down before. Given that all of the printing on the exterior of my power supply’s would only be upright wi the the fan up, I thought that was the only way to mount it. My current case has the grate on the bottom so I mounted my PSU “upside down” and at least I know that it won’t hurt anything.
I tried both configurations, i wanted to see if the psu up inlet would improve air flow and draw more hot air away from the gpu, yes it would heat up the psu and have a de rating affect but the psu is oversized so this wouldn't be an issue. The result was the exact same gpu temp in both configurations which was surprising since you would think this would assist the gpu exhaust. So i left is in the down inlet standard config.
That is indeed weird.
Although, out of all the fans, I have the hardest time understanding intake/exhaust and airflow of the GPU fans.
RIGHT ON JAY! Some of us are not pros and are new to PC builds. And many (apparently) are PC geniuses that can tell you how every part you've ever bought is the wrong one.
Gilbert Quintanar well duh because everything you know is wrong and jay cant be right cuz the internet is never right
OMG, some of the Reddit comments I've read...wow. Like, some of us are building a PC for the first time and don't know everything about everything...which doesn't automatically make us morons.
@@Sampson2012bot That is true. Not knowing everything about everything when building a PC for the first time is not what made you a moron. (there are other factors at play)
Thanks for the video. For myself, I always mount it with the fan facing down simply so that the power supply is protected from potential water leaks.
Dang, nice PDXLAN shirt! I attended twice when I was in high school, probably around 2005 or so. It was the first time I went to a LAN party bigger than my friend's basement. What an experience!

(that was supposed to be a negative reply :D )

this is a reply. not positive, not negative, and not neutral
Tuchulu Stahp youre forcing me to give a negative pressured reply
Please tell me you were referencing Def Leppard with pour some sugar on me?
Also, what many people forget with PSU fan up or down is that it was only relatively recently that case manufacturers put the PSU on the bottom, and the top mounted PSU's were almost always mounted with the fan facing to the inside of the case, and if it didn't negatively affect airflow or temperatures with less efficient PSU's then, why would it affect them now?
I've run PSU's in both fan up and fan down orientation, and my takeaway from that is that I prefer fan facing up because it minimises dust intake to the PSU which extends it's lifespan, and it also looks better with the fan grill facing up.
Ah Jay! You are the best man , I mean like you are always the most accurate and on-point with pc building and tech gear information on the grand ol RUclips. I seem to be having a problem with a pc case (AZZA CSAZ-211 Black ATX Mid Tower) that I bought and please brother if you have any spare time I really am in desperate need of some expert advice
every question I have I find you with an answer. Thank you Jay!
I've always wondered why more water coolers don't use non conductive liquids, like the XSPC XS-EC6-CL Non Conductive Coolant. Is it less efficent than distilled water? I think a test is in order Jay. Whilst you are at it, what actually happens if this stuff spills on your motherboard, or your PSU?
TLDR:
Fan down: with power supply shroud, or water cooling
Fan up: on carpet, one exhaust fan, most setups
water cooling......

It would be good if you did temperature tests in various areas of the case to support your claims.

@Bruce Wayne You arent gonna win a argument with insults... Kindergarden went away years ago
@@christopherjames9843 That escalated quickly...
Bruce Wayne clearly no one held your hand as a kid, does it make you feel all tough now?
I think it's simple. Having the cooler upwards, means pulling warm air into the psu. Probably the temperature inside the case decreases, but the PSU cooler is not for cooling the inside of the pc. It needs fresh air and it can get fresh air only from the downside. That's why mostly every case has an opening for the psu cooler at the bottom. Now tell me I'm wrong?
Sup Jay!
What do you think about a video on how you store and organize all your parts? I'm sure I'm not the only one who has a bunch of parts laying around everywhere and probably need to implement some sort of organization method.
Thanks!
I had to flip my psu to fix some squeaking issue with my psu fan and I was wondering it was a bad idea but now I am no longer worrying, thanks!
We're supposed to mount the power supply, i usually just let it hang at the top of my case
Nice something to watch before going to bed
Fantastic, concise overview, thank you!
Hey Jay cool video as allways, appreciate you sharing your wisdom onto us. But i got two questions. 1 in order to get neutral preassure (as you mentioned favourable) can you somehow control the psu fan speed, say if you have non pwm case fans which are dirrenet rpm. 2 how does having a psu facing up (as an additional exhaust fan) affect overall temps in different scenarios eg. blower style gpu vs open air gpu.
Noise is a factor too, esp. in a very quiet system. Having the fan inside the case, it has no noise direct escape path. Even if it has to work a bit harder, it is quieter. Also the fans are more effective blowing down than blowing up (where the gravity and the push work against the seal holding the blades)
You realize that fans in a computer case are for cooling. Warm air rises. Why would fans be more effective blowing down? (this is not an actual question and is very sarcastic)
@@paulmartin2348 There are new fans that blow in the opposite direction so they work OK blowing up. But the mechanics of the fans are such that it is much more effective (and thus quieter) when blowing down, against the gravity. If the fan blows up, it is resting on the O-ring that holds the spindle. Plus the air pressure.
The convection is not a factor in a case, there is far too much of air movement inside. The fans can easily overmatch the convection.

Very very helpful and informational. Thank you!
Nice video. Great explanation and advice.
One thing I do not agree with.
It's almost impossible to have a loop of suction air from the power supply if it's mounted with the fan downwards.
It is advicable to have the intake air fans at the bottom or in the front of the PC, because the warm air is lighter than the cold air. That's why they changed the position of the power supply as we remember years ago it was at the top.
If you mount the power supply with the fan downwards(not on carpet) it will always suck a cold air, because it's heavier and it stays at the bottom. The warm air that goes out from the power supply wil immidiately go up so it's impossible to be sucked in again unless you have a intake fan on the back top case .
Mounting the power supply upwards it's not a bad thing too if you have a infront intake fans. But having a powerful GPU might cause a slight problem since the power supply will always suck it's not so much cold air.
It actually all depends if you want to use your powwer supply as a exhaust fan too or keep the supply in a good condition.
If it’s got vent holes for it I always install down
Mounted the PSU up. Just got a new M2 NVME which I tried to install. Dropped the M2 screw down in the PSU. Didn't want to open the PSU. But the screw got stuck inside the PSU. Took forever to get it out. Had to unscrew the PSU and flip it upside down and shake it for a long time.
I remounted the PSU down now. And will do it going forward.
Lay PC down if you doing work. I have 3x A12x25s at front. Air only in via filtered front. Air out via rear fan, GPU vent and PSU. Every other hole, no matter how small taped up, even PCI slot cover holes. PSU fan is hybrid and never needs to come on. The positive pressure from front fans is huge and is almost enough to blow lighter flame out if placed near psu vent. Front fans dialed in with noctua fan controller. Highest speed without being audible in dead of night. GPU is always 'actively' cooled via the flow too. Clean case, silent, cool.
Lucky it was just a screw, if the P/S was the right way up passive air flow would do the work, cooler air falling as warm rises ...
Same happened to me. That's why I'm watching this video 🤣🤣🤣

I built my first PC a year ago, and now I'm building an office computer. JayzTwoCents has been my "go to" for PC build questions.
these are the real questions in life
Just a warning.. I mounted mine with the fan faced up since my PC sits on a carpet, and while mounting the backplate of an AIO cooler, a washer fell into the crevice between the motherboard and case, then landed in the power supply. I didn't realize this until it was too late. After testing my PC for a bit it was fine. I brought it upstairs to my normal spot, flicked the switch then hit the power button, and was then greeted with a nice gunshot sound paired with a white flash as soon as I hit the power button... Though it was my own stupidity in running the PSU without finding the missing washer... I'm never mounting my PSU with the fan faced up again. I ran into this video shortly after it happened so I don't know if the components are okay yet. :/
Sirei Talk Ouch..

@@computethis7128 Mine hasn't leaked, so I can't really say whether it's worth it or not.. But so far it seems worth it for how beautiful it looks and for how well it performs.

"In the name of love!"
Ok, now you need to tell us how you balance the fans!
After a few reboots because of the rectifier side overheating I figured the dust filter is better gone (those fans lose like half of their actual power when the filter is present, so better just vacuum-clean the PSU from time to time). Also whenever the intake is facing down, swapping out the standard legs with somewhat longer ones allows to greatly improve the airflow and reduce the amount of dust that reaches the board.
Ty Jay, I actually had the upside down psu with plush rug under it
been building systems for 5 years this has never crossed mind im gonna now flip my psu.
flip the tower too for better airflow.
tootsie|troll® thanks I will post benchmark results tomorrow.
!RemindMe 1 day
@@MATTW3R 2 years later still waiting on results.
Vaughn Armstrong lol honestly it worked my PSU is still sitting with the fan facing up since this post and dust hasn't caused any sort of issue temps never changed inside of the pc I tried flipping the case but I couldnt reach the USB ports like that so test was inconclusive.
I've had a couple of power supplies die prematurely from being fan side down. All Corsair models.
My theory is that the "smart" fan on Corsair PSUs won't turn on unless your computer is drawing a certain power level. Even if the power supply gets dangerously hot the fan won't kick on. The temperature safety limit will always be hit before the fan is turned on.
When flipped fan side up, natural convection is enough to solve the problem entirely.
great vid J. That was enlightening
It’s funny I just saw this video and the case sponsor you have is the case I actually used about a year ago for my build. I would love to have my case on my desk but I have a small space so I leave it on the carpet. But I did get some wood at Home Depot and it works great. I actually used this PSU advice with my nephews build in the nzxt h500 case to reduce the gpu temp that could come from the gpu. Thanks again for the advice because his system does run at pretty good temps.
